Patent number: 9791041Abstract: An automatic transmission control apparatus includes an engine generating power by a combustion of fuel; an automatic transmission provided with a friction element including a clutch and a brake and changing the power generated in the engine into a torque required depending on a speed by an engagement and release of the friction element to be output; an accelerator pedal position sensor detecting a position signal of the accelerator pedal; and a controller determining whether a vehicle is in a rapid acceleration state from the position signal of the accelerator pedal detected from the accelerator pedal position sensor and correcting a control hydraulic pressure of the friction element if the vehicle is the rapid acceleration state. Since the friction element control hydraulic pressure is controlled depending on the operation speed of the accelerator pedal, the shift responsiveness may be improved.Type: GrantFiled: November 19, 2015Date of Patent: October 17, 2017Assignees: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventors: Dong Hoon Jeong, Chong Tae Yang

Patent number: 5917675Abstract: A cassette loading and unloading device for use in a video cassette recorder ("VCR") comprises a door hinged at the front panel such that it is inwardly swingable, a first and a second side walls, each of which has an upper and a lower guide slots, a cassette holder having at each side surface an upper and a lower slide pins which are respectively fitted in and movable along the upper and the lower guide slots of the side walls, and a first and a second pivot arms tightly fitted on both ends of a shaft rotatably held by the side walls. The first pivot arm has a gear portion at a bottom end. A door opener is rotatably mounted onto the first side wall adjacent to the first pivot arm. The door opener is linked at an upper portion to the door and at a lower portion provided with a cam follower. A lengthwise movable elongate bar has a rack portion engaged with the gear portion of the first pivot arm and a cam provided with a cam surface.Type: GrantFiled: November 24, 1997Date of Patent: June 29, 1999Assignee: Daewoo Electronics Co., Ltd.Inventor: Chong-Tae Yang

Patent number: 5810275Abstract: A reel table driving device, for a video cassette recorder, comprises a pulley, a driving gear rotated with the pulley, and a first and a second idle gears rotatably fitted on a post fixed to a bracket pivotably mounted to the deck. The first and the idle gears are frictionally coupled to each other through a friction member. The pulley is provided with a boss tightly fitted on a shaft rotatably held by the deck, the boss having a pair of opposite guide groove axially extending. The driving gear has a pair of protrusions inwardly protruding from an inner surface thereof and is fitted onto the boss of the pulley in such a manner that the protrusions are inserted in the respective guide grooves. The driving gear is movable up and down along the guide grooves and rotated together with the pulley by the interaction of the protrusion and the guide groove.Type: GrantFiled: July 21, 1997Date of Patent: September 22, 1998Assignee: Daewoo Electronics Co., Ltd.Inventor: Chong-Tae Yang

Patent number: 5730383Abstract: A reel table braking device for use in a video cassette recorder having a deck and a reel table rotatably fixed on the deck through a shaft. The reel table braking device comprises a brake assembly mounted on the shaft of the reel table and movable along the shaft between the reel table and the deck, and a slide plate provided with a first and a second urging means having different height from each other. The brake assembly includes a main brake, a sub brake, and a compressive spring fitted on the periphery of the main brake. The main brake has at least one elastic hook and a bottom plate. The bottom plate protrudes from the periphery of the main brake and supports the spring. Furthermore, the sub brake has at least one hook seat corresponding to the elastic hook, is fitted on the main brake in such a way that the hook is inserted in the hook seat, and is biased upwardly by the spring.Type: GrantFiled: March 26, 1997Date of Patent: March 24, 1998Assignee: Daewoo Electronics Co., Ltd.Inventor: Chong-Tae Yang
